I have some directorys with Umlaute like "Bänder" I want to read in. From this question here Python not able to open file with non-english characters in path , I know that I have to convert my Path to utf-8

f = 'data\\Bänder'
s = f.encode('utf-8')

#works
open(s)

#does not work
img = cv2.imread(s)

Using the encoded version results in the error:

TypeError: bad argument type for built-in operation

Casting it back to a string, or decoding it will lead to no image read

I am using Windows 10, Python > 3 and Spyder / Anaconda

You could always just load the contents of the image file into a buffer and run `cv2.imdecode` on that. – Dan Mašek Mar 31 '18 at 19:03
thank you for your answer, so basically reading in the image data with the help of the bulitin function of python "open" ? – Kev1n91 Mar 31 '18 at 19:06
On Ubuntu umlauts work without any conversion. Are you working with windows? – zindarod Mar 31 '18 at 19:15
I am on Windows 10, I added more details to the question – Kev1n91 Mar 31 '18 at 19:17
Hmm, it seems that on my Win 10 box, I can make `cv2.imread('B\xe4nder.png')` work. i.e. using a Latin-1 codepage. – Dan Mašek Mar 31 '18 at 19:24
so instead of using the encode 'utf-8' I should use latin-1 ? – Kev1n91 Mar 31 '18 at 19:41
